3 claims'. (01.160-232) This invention relates to a door and more particularly to a door of the type suitable for use in various structures such as, for example, a telephone booth.

VIn general, the broad object of this invention is to provide a door comprised of elements which may be rapidly fabricated in quantity and assembled With ease by unskilled workmen.

u A further object of this invention is to Yprovide a door having a minimum number of individual parts without any lsacrifice of structural strength.

An additional object of this invention is to provide a folding leaf door with interlocking hinges which eliminate the necessity of using separate hinges. y Y Y A further object of this invention is to provide a structurally strong door which may be formed without the use of welding, soldering or brazing.

A further object of this invention is to provide a door having novel means for securing a Window therein. Y

The novel features of design and structure, by means of which these and other objects which will become apparent are accomplished, may be best described in connection with the accom'- panying drawings which show an embodiment of this invention adapted for use in connection with a telephone booth. In the drawings:

Fig. 10` is a section taken looking downnon a horizontal plane through a telephone booth be- All references to the left or right hand in the following description are based on a view taken from the rear of the door as in Fig. 1.

A door 2 has a right hand leaf 4 and a left hand leaf Leaf 4 has a front panel 3 and a rear panel 5. Leaf 6 has a front panel l and a rear panel 9. The panels 3, 5, 'I and 9 are formed from stampings le, 8, I2 and I4, respectively, which are shown in Figures 4 through 7.

En order to form the right hand leaf 4, rear panel 5 is first formed from stamping 8 shown in Figure 4. The stamping 8 is bent at right angles along the dotted lines indicated at I6 and I8 to form horizontal flanges 20 and 22, respectively (Figure 8). By bending the blank 8 at right angles along the dotted line indicated at 24, a vertical iiange 26 is formed. The flange 26 is then bent along the dotted line 28 to -form a small flange 38 perpendicular to the flange 25. This rear panel is completed by bending the blank along the line 32 to form the hinge portion 34 and by bending the ears 35 to form cylindrical pin-receiving hinges 37.

The front panel of the right hand leaf 4 is formed by rst bending the blank I8 (Figure 5) at right angles along the dotted lines indicated at 36 and 38 to form horizontal flanges 40 and 42, respectively (Figure 8). These flanges are then bent along the dotted lines indicated at 44 and 45 to form vertical flanges 48 and 5G. The blank I0 is then bent along the dotted line 52 to form the substantially U-shaped opening 54. This exterior panel is completed by bending ears 56 to form cylindrical pin-receiving hinges 58.

As shown in Figure 8, the completed panels 3 and 5 are positioned for assembly. In order to assemble these panels, panel 3 is moved to the left in such a manner that the flange 40 will slide over the flange 2B and the ange 42 will slide under flange 22. When the assembly is completed, flanges 48 and 55 bear against face 6D of panel 5, and flange 3i) fits securely in the U-shaped opening 54. In addition, the hinges 58 are aligned with the hinges 37 and hinge panel 34 abuts against panel 3. Further, Window opening 52 in panel 5 and an openingl 64 in panel 3 are now positioned opposite each other. t

The blanks l2 and I4 and the panels I and 9 formed therefrom are mirror images o f blanks Ill and 8 and panels 3 and 5, respectively, with the exception that the hinges 66 and panel 'I and the hinges 68 of panel 9 are located so as to be alignable with and ll the spaces between low the lintel to show how the double leaf door pairs of hinges 31 and 58. The formation of panxnay be installed in a telephone booth.

els 'I and 9 is consequently identical to the fore 3 mation of the above described panels 3 and 5. The exterior panel 'I is formed by bending the blank I2 at the lines indicated at 10, 12, 14, 16 and 18 to form flanges 80 and 82, U-shaped opening 84, flanges 86 and 88, respectively (Figures 1-3) Ears 90 are bent to form hinge 66.

The inner pan-el 9 is formed in a manner similar to theformation of inner panel by bending the blank I4. along the lines indicated at 92, 94, 96, 98 and |90 to form flanges 102, |04, |96, |08 and hinge panel H0, respectively (Figures 1-3). Ears i l2 are bent to form hinge 68.

The panels 'l and 9 are assembled to form the leaf 8 by sliding the panels together until the hinges 66 and 68 are aligned and flange 198 is locked in the opening 8d.

1n order to complete the formation of the door 2, the aligned hinges 3 1 and 5B of leaf d are brought into alignment with the aligned hinges GSjandS of the leaf 'A hinge pin illihaving a knob ii is driven downwardly through the hinges. It should be noted that the hinge pin is not only utilized for hingedly connecting the leaves 2" and but also to loci: panels fi andv 5 and'paneis "i and 3 to each other respectively.

To secure a pane of glassY in ea n leaf, a novel molding' strip iiii formed of flexible rubberlike material is utilized. The molding strip lf3 has on its inside 28 a pair ofslots 22 and i251 which are of the same width the sheet metal usedl to` form the doors and are spaced apart a distance equal to the space between the front and rear panels of a leaf. Theou side 26 has a slot 28 suitably formed tc receive a pane of glass 136.

As shown in Figure molding strip il 3, which is used in the left hand leaf, holds a pane of glass H36 in slot 623, while, in turn, the strip itself is held in position by virtue of the fact that the panels 9v and 'E are entered in slots 52?: and 22,

respectively. Due to the flexible nature of the molding strip, glass may be secured in position without difficulty by following' the method of working the glass E35 into slot 23 and the panels 9 andy l into slots 12d and prcgressively. Thus, as the molding strip is'secured to a smf l portion of the leaf, that portion of the pane of glass which is opposite the part of the leaf secured in the strip is forced into slot 125; By following this procedure in successive increments, a pane of glass E30 may be secured in the door without difficulty.

The door 2 may be secured in a telephone booth structure H32 in any of the conventional manners of securing a double ieaf door in a telephone booth such as, for example, by the means shown in my prior Patent No. 2,208,166, issuedV July 16, 1940, which is illustrated in Figure 10. As shown, a bracl-et 84, which is secured to leaf il, carries a roller |38 which travels in track 138. Track 38 is secured to walls 39 and Mi. The leaf 6 is secured to wall i453 of the telephone booth 32 by hinge M6. A knob M2 is secured to leaf' to provide means for opening and closing the door from the interior of the telephonebooth.

It will, of course, be obvious from the embodiment here illustrated and described that a single leaf door may be formed in accordance with this invention In the case of a single leaf door, theI aligned hinges of the panels forming the leaf are utilized to hingedly secure the door to the supporting structure.

1t will be evident that the features of the invention may beembodied in structures other Y than that illustrated, and accordingly the invention is not to be regarded as restricted except as required by the following claims.

What I claim and desire to protect by Letters Patent is:

1. A door having two leaves, each leaf having a pair of spaced panels, hinges on the panels formed integrally therewith whichareirnalignment, and a hinge pin passing through vthe hinges of all the panels thus locking both the panels and the leaves together, each of said pairs of panels being additionally locked together along their other sides by abutting and interlocking flanges.

2. A door comprising a first panel having along each vertical and horizontal edge an inwardly extending. flange, integral hinge members on the vertical edge of one of said flanges extending inwardly from one vertical edge of the panel and a locking flange extending from the inner edge of' the flange extending inwardly-from-the second vertical edge of thev panel, a second panel having an` L-shaped flange extending from the top edge so as to overlie the top flange of the rst panel and lie againstfthe face of the first panel, an ,L-shapedl flange` extending from the bottom edge s0 asto lie-*under the bottomrflange of the first panel and against the faceof the'- first panel, integral hinges along onevertical edge which are alignedv with the hinges of thefirst panel, a slot for the reception of the locking flange-anda hingepinY through the hinges.

3. A door having two leaves, each leaf come prising a first panel having along eachv vertical and horizontal edge an inwardly extending flange, integral hinge members on` the vertical edge of one y of said` flanges extendinginwardlyfrom one vertical edge of the panel and a locking flange extending from the in-ner edge of the flange extending inwardly from the second vertical edge of the panel, a second panel having an L-sha-ped flange extendingfrom the top-edgeso as to overlie the top flange of the rst panel and lie against the face ofthe first panel, an L-shaped ange extending from the bottom edge so as to lie'under the bottom'flange of the-first panel and against the face of the rst'panel, integralhinges along one vertical edge which are Aaligned with the hinges of the first paneLand a slot for the reception of the locking flange, allof the hinges of the four panels being' aligned and having a hinge pin passing through them so as to hingedly connect the leaves together. v
